Outer shell
The outer shell of the Schuberth S2 is offered in two helmet shell sizes and combines an aerodynamically optimal shape with excellent protection. It is manufactured using Schuberth's typical compression molding process and thus permits great stability and a low weight.

Shell material: S.T.R.O.N.G. fibre

Helmet shell technology from SCHUBERTH permits low weight

Glass fibre with a special resin added is compressed in a vacuum at high pressure to form a helmet shell which is exceptionally sturdy.

Inner shell
The helmet shell of special EPS foam is modular in design to ensure optimal shock absorption. This complex segmentation guarantees enhanced force absorption and distribution and maximum safety.

Made of specially optimized EPS foam

Complex multizone foaming allows optimal shock absorption

Inner lining
A special inner lining of the S2 which was developed according to the innovative Comfort Fit concept ensures that the helmet fits comfortably and securely in all situations.
The combination of carefully selected COOLMAX® and Thermocool® materials and the additional use of Interpower® coatings also make the inner lining a highly-effective moisture removal and cooling system.

Precise setting of the chinstrap length through adjustment on both sides.

Micro-lock ratchet lock

Reflex pads
The silver-colored appliques of reflective material which are in included in the nape zone of every SCHUBERTH helmet ensure that the motorcyclist can be seen better, especially in twilight or at night.

Anti-Roll-Off System A.R.O.S.
The Anti-Roll-Off System (A.R.O.S.) especially developed by SCHUBERTH is provided as a safety feature in every SCHUBERTH motorcycle helmet. It ensures that provided the chinstrap is closed and correctly adjusted:

The helmet cannot pivot off the head from behind

The risk of contact between the chin section of the helmet and the chin or throat of the rider is minimized due to the small angle of tilt and

The consequences of the helmet coming into contact with the chest as the result of an accident are reduced.

The helmet also has Reflex areas which improve visibility in the dark and thus contribute to your safety.

Aerodynamics
High-performance aerodynamics
The S2 is specially set for the riding posture of motorcyclists on tours/sporty tours and remains stable in the air flow. The special shape of the helmet shell and the edge of the helmet closure ensure appreciably enhanced contact pressure. The S2 creates practically no upward lift, even at higher speeds. In addition, the S2 also offers lower air resistance and high directional stability. The buffeting is also significantly reduced on naked bikes.

Acoustics
Aeroacoustics of the S2
A quiet helmet means active safety for the motorcyclist: this permits the rider to concentrate on riding – particularly at higher speeds.
Many hours in the Schuberth acoustics wind tunnel have ensured that the S2 is quiet. The comprehensive acoustics package with optimized helmet shell, wind deflector and ergonomic shape of the neck padding make the S2 – at 85 dBA – one of the quietest helmets of all.

Acoustics package makes helmet quiet

Installation of a wind deflector enables the aeroacoustics and consequently the noise level to be improved still further.

Only 85dB(A) at 100 km per hour (with naked bikes)

Basics
Sound intensity is a phenomenon which can be explained logarithmically/mathematically. A 10 dB(A) jump in noise level is perceived by the human ear as a doubling of the noise level. Conversely a drop of 10 dB(A) is perceived as a halving of the noise level. Physically these changes in the perceived noise level already occur at an increase or decrease of 6 dB (A). This means that the increase/decrease in the physical load is higher than the one perceived.

Optimization
Aeroacoustics are influenced by:

The position of the helmet in the air flow, depending on the driver's size and riding posture and the motorcycle's fairing

Fit of the helmet: differences in the anatomy of the wearer's head, neck and shoulder areas

Tips

Change the position of the windscreen

Close the gap at the bottom of the helmet, e.g. using a scarf

Ventilation
Innovative ventilation system
The S2 is equipped with an innovative ventilation system. The combination of multipath channels in the EPS foam shell and the head, chin and mouth ventilation ensure that fresh air is distributed efficiently throughout the entire head area. The fresh air which enters via the forehead ventilation is conducted through the inner shell's air channels well beyond the back of the head to the rear of the helmet. The low pressure prevailing at the rear of the helmet causes the interior air to be extracted constantly through the air outlets and the special mesh fabric in the neck padding.

O2 ventilation

In cold weather it often occurs that with closed air supply the motorcyclist's neck zone becomes sealed off by hoods, scarves or neckerchiefs.

The concentration of carbon dioxide inside the helmet is a key safety criterion for preventing symptoms of fatigue and the thinning of breathable air.

No negative effects on health need be feared as long as the CO2 concentration remains below 3.5 %.

The maximum level of CO2 concentration at the workplace is 0.5 %

Even when the neck zone is sealed off by hoods, scarves or neckerchiefs, this helmet guarantees that the CO2 concentration remains below the 0.5% limit as from a speed of approx. 30 km/h.

In cases where the helmet is completely sealed off by hoods, scarves or neckerchiefs, the visor ought to be opened (city-travel position) for safety reasons when idling, for example at traffic lights, or traveling slowly.

SRC-System™-ready
The S2 is by default equipped to accommodate the SCHUBERTH SRC-System™ S2 (available in summer 2012). To guarantee ideal radio reception for you, the S2 is already equipped with two integrated antennas to boost reception and a Bluetooth® connection

Optimum reception quality at all times

Having ridden only 120 miles so far here are my initial thoughts on my new Schuberth S2:

Size / Fit: Normally I am a small when it comes to helmet fit. I tried on both the small and medium sizes (same size outer shell on both) and found the medium to be more comfortable. The padding (which is fully washable and removable) does appear to hold its shape well, and is certainly far better than my old Nitro helmet. The helmet was immediately comfortable and having spent a constant 2 hours with it on I can report no uncomfortable pressure points.

Visor: The visor is reasonably thick and comes fitted with a clear pinlock insert. There are tabulators(small proud diamond shapes) on the upper rim of the visor that are supposed to reduce wind noise/whistle. A bit of a gimmick in my opinion. The visor seals well against the helmet and has a small lock that keeps it securely down, a nice feature. There are 6 positions between fully open and fully closed. Movement of the visor between these positions is positive. Getting the visor into the city position, which is just open and no more can be a little difficult with thick gloves on, but its possible with a little practice. The visor is easily removable without tools. The internal sun visor is dark enough (80% dark) and easily operated (even with thick gloves) via a lever on the lower left side of the helmet. Schuberth say that it is infinity adjustable, which it is, but I doubt that you would use it in any positions other than fully up or fully down. I felt that it would be nice if it could come a little lower however as the sun is generally upwards the it does what it is supposed to. There are small tabs on both the right and left hand sides of the lower edge of the visor to aid moving it up, some helmets only have them on one side, so that is nice to see. My local dealer thinks that the visor may be the same as the C3. If that is the case then getting a replacement should not be a problem.

Ventilation: This helmet is extremely well vented. There are several small holes that are permanently open on the chin vent, keeping a constant airflow moving over your face, distracting at first but I soon got use to it. The chin vent is simple to open, even with gloves on, and should stop any fogging (should you require it (pinlock not working? doubtful!). When you get up to 30mph or above you probably wont want this vent open, and its simple to close. The top vent is again easy to operate with gloves on, although requires a little more practice than the chin vent. It has 3 setting (fully open, half open and fully closed). There are 2 small flaps on the helmet lining that you can fold back which ensures a constant stream of cooling air right onto the top of your head. Not to your taste? Then just fold them out again (it takes seconds with the helmet off) for a less severe cooling experience. There are several extraction vents on the rear of the helmet that get rid of the air that has been circulated. Make no mistakes this is a very well ventilated helmet. I will be interested to see how it copes in a downpour, with it being constantly vented at the front. Winter / cold weather riding might be interesting ! (the addition of a thermal balaclava should sort this tested in the summer and there was a noticeable difference)

Chin strap: Micro buckle design, which is easy to fit, adjust and remove. It features Schuberths AROS fixing technology, meaning that the strap is also attached at the rear of the helmet. This is designed to be less likely to roll off in the event of an accident. Similar technology has been used on bicycle helmets for a number of years now and does appear more secure. It does not effect the fit of the helmet. The only small issue I have encountered occasionally with the strap is that it appears to be a little too far back and there is the occasional pressure on my windpipe from the strap. More fiddling required for a slightly better fit I think. Ensuring that the helmet is adjusted so that the micro-adjust buckle is all the way home does improve things.

Stability: Little to say other than I have had no issues at all and the helmet appeared stable at all (legal) speeds. No unwanted lift, even at speed. I was even pleasantly surprised when I moved my head left to right at speed (this used to flip open the visor on my Nitro not fun).

External noise: Schuberth do appear to pride themselves on their helmets ability to keep external noise to a minimum. I have a race can on my bike and its somewhat noisy The Schuberth does a good job of keeping this noise to a minimum (that said I will always ride with ear plugs in). The S2 does come with a removable wind deflector (re: chin curtain). Without this fitted I felt that there was too much wind noise. When the wind deflector is fitted there is a noticeable reduction in wind noise. Be careful with the wind deflector though, its can deform out of shape when fitting/removing the helmet (it attached to the inside of the front padding with Velcro)

Overall: Very happy with my purchase and a real improvement on my previous helmet. It is a great helmet to wear and is very comfortable as well as being packed with features. Only the slightly too far back chin strap and sun visor not coming down quite far enough stop this from being absolutely perfect, however I am really splitting hairs. Its also expensive. Each to their own though.

I needed a new visor with the Pinlock fog free visor. The Pinlock on my 4 year old C3 no longer sticks to the visor. Allowing water to get lodged in between and degrading my vision in the rain. I saw this advertised as a Pinlock Visor and the image shows the Pinlock inner visor installed. As received it did not include the Pinlock Visor, just the Schuberth Visor with Pinlock mounting pins.I was happy to get my new visor but now have to go find a new Pinlock inner visor.FYI, when ordering, order a Pinlock Inner Visor too
